FOUNTAIN-PEN.

7 Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed August 11, 1914. Serial No. 856,265.

To all whom it may concern:

Be it known that I, FREDERICK C. Bins, a citizen of the United States,residing at Macon, in the county of Bibb and State of Georgia, haveinvented new and .useful Im-,

provements in Fountain-Pens, of which the following is a specification.

The present invention has reference to fountain pens, and it proposes,briefly, an improved cover for pens of this general type which is soconstructed as to enable it to fit upon either end of the pen and, whenin place upon the point end, to provide for an extensive aircirculation, which serves to prevent sweating and other pen troublearising from heating.

An embodiment of the invention illustrated in the accompanying drawing,whereof Figures 1 and 2 are, respectively, a plan View and a sideelevation of a fountain pen equipped with the improved cover, the latterappearing in section in Fig. 2; Fig. 3 is an enlarged, transversesection taken on line 33, Fig. 2; Figs. 4 and 5 are views similar,respectively, to Figs. 1 and 2, but showing a modification; and Fig. 6is a detail view of the cover in the modified form.

The pen 7 represented in Figs. 1 and 2 is, in the main, of conventionalform and, hence, requires no extended description. Its barrel, however,is provided with a rigid centrally-located, circumferential rib orcollar 8, which is approximately semi-circular in cross-section andwhich may be either of the same material as the barrel or of any othersuitable material. I

The pen 7 depicted in Figs. 4 and 5 is substantially identical in itsessentials to that previously described, and is likewise provided with acollar 8. The cover for the pen is preferably in the form of acylindrical tube which is closed and rounded at one end and having itsopposite end fully open and provided with a retaining device forcoaction with the afore-mentioned collar; it may be constructed in anydesired length and from either friction or spring metal, or in fact ofany other material which may be deemed suitable. In the form disclosedin Figs. 1, 2 and 3, the cover 9 is assumed to be made from springmetal, and its open end or mouth is formed with a longitudinal extensionor tongue. 1.0 which. in turn. is provided with a seat or depression 11,this tongue constituting the retaining device above referred to. Thetongue 10 is integrally formed with the open end of the cover and isnormally straight and in the same plane as the body of the cover so asto avoid the least obstruction to insertion of the op osite extremitiesof the pen 7 asa whole lnto the said cover. The said tongue, as will beunderstood, projects beyond the end of the cover whereon it is formed,and 1s designed to have a snap engagement, so

to speak, with the collar on the pen, its seat 11 fitting over thecollar, as shown in Fig. 2. Opposite the tongue, there is provided, inthis form of cover, a second tongue 12, which may be produced byslitting the cover, and which is designed to bear against the surface ofthe barrel when the cover is fitted upon either end of the latter, andprovides a resilient means diametrically opposite the tongue 10 topermit yielding movement of that part of the cover which engages the penbody so as to relieve the said portion of the open end of the cover ofundue strain by reason of the tension exerted thereon when said tongueengages the rib or collar 8. The diameter of the cover is somewhatgreater than that of the pen barrel. so that an air chamber 13 will beformed between the side walls of said barrel and cover when the latteris in place, (see Figs. 2, 3 and 5), such chamber communicating with thespace or chamber 14 formed within the cover at the closed end thereof.lngress and egress of air to and from the first-named chamber arerendered possible owing to the provision of a pair of vents or apertures15 which, in the present construction, are produced by cutting away thecover at opposite sides of the main or collar-engaging tongue 10. thesevents tapering in width from their outer to their inner ends. In thisway, aconstant circulation of air through the cover and around thecontained portion of the pen is insured. with the result that the pen iskept cool and sweating and kindred troubles are avoided. Also, owin tothe difference between the diameters of the cover and barrel, only asmall part of the latter will be in contact with the cover which thusassists in brass or other friction metal, and. with the 1 that thesecond or auxiliar exception depression 1. are

tongue and seat or omitted, is otherwise. identical with the first, thecorresponding parts or features being indicated by the same numerals asin the said first form, but with the rime mark applied thereto. Thecover, as a ove stated, may be applied to either end of the pen, and ismoved inwardly thereon until the tongue 10 or 10 projects across thecollar and the adjacent side of the latter engages the edge of thecover, the said collar thus acting as a stop to limit the movement ofthe cover.- In the case of the spring metal cover, the

seat 11 in the tongue 10 snaps over the collar, and the said cover isretained b the pressure of this tongue and of the auxlliary tongue12,while in thecase ofthe brass cover, the tongue "10 has a frictionalengagement with the collar. In the latter form, there is also provided.upon the front end of the barrel a second circumferential collar 16',which is designed to hold the pen point in position within the cover 9;that isto. say, this second collar will serve to' center the pen pointwithin said cover during its insertion therein-and, obviously, duringthe time that the cover is in closed po-- sition, thus maintaining thesaid point as far as possible away from the wall of the cover. Tofacilitate withdrawal and subsequent re-insertion of the pen point andspoon, a removable cross-pin, or the like, may be passed throughregistering openings in said parts, as shown, this pin being indicatedin Fig", 2 by the numeral 17 and in Fig.4 by the numeral 17.

Having fully described 'my invention, I

1. The combination with a fountain pen,

of a circumferential collar fixed thereon and having a convex surface,and a'resilient tubular cover having one end fully open and providedwith an integral retaining member projecting from the said open end andprovided by forming inwardly extending slots in the open end of thecover, the retaining member projecting beyond the open end of the coverto engage the convex surface of the collar, the remaining vportion ofthe open end of the collar being straight to abut against thesaid'collar and the open- 7 ings forming the retaining member alsoserving as vents to admit air into the cover, vthe cover beingapplicable to either end of the pen to bear upon and project over. thecollar in opposite directions.

2. The combination of a fountain pen having a fixed circumferentialcollar on the intermediate portion of the body thereof,

said collar having a convex surface, and a tubular cover completelyclosed at one end and fully open at the opposite end and formed ofresilient material, the cover at the open end being provided withinwardly projecting openings to form an integral tongue which extendsbeyond the open end of the cover and formed with a depression in itsunder side to engage and receive a portion of the convex surface of thecollar,

the said tongue being normally straight and in the same plane as thebody of .the cover, the remaining portion of the open end of the coverbeing straight and abutting against the collar to limit the movementofthe cover, the cover being reversible or apnlicable to'either end ofthe'pen body and held againstaccidental disengagement solely by thefrictional bearing of the tongue on the collar.

3. The combination with a fountain pen having a barrel with anintermediate fixed circumferential collar having a convex surcent to thecollar and whereby the portion of the open end of the coverdiametrically opposite the tongue is forced in close engagement with thebarrel and the collar.

- 4. The combination of a fountain pen having a fixed circumferentialcollar provided upon the intermediate portion'of its barrel and formedwith a fixed surface, and

a tubular cover having one end fully openv and provided withan integralyielding retaining member projecting outwardly beyond the fully open endof the cover and normally in the same plane as the body'of the cover tomove over and frictionallv en'- gage the .saidcollar, the remainingportion of the open end of the cover being straight and said open endprovided with a yielding tongue at a point diametricallv opposite thesaid retaining member to relieve the cover of strain when the retainingmember en- 7 gages the collar. y

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
